Product Description

Specifically designed for the R53 Cooper S, this Milltek cat-back aftermarket upgrade seamlessly blends performance enhancement with an upgraded aesthetic. Constructed from high-quality stainless steel, the Milltek cat-back system ensures durability and resistance to corrosion. The incorporation of mandrel-bent tubing in the exhaust design promotes smoother airflow, effectively reducing restrictions and backpressure. This thoughtful engineering is aimed at potential gains in horsepower and torque, offering a tangible improvement in the overall performance of your Cooper S.

One of the standout features of the Milltek cat-back exhaust is its carefully tuned exhaust note. As you hit the accelerator, you'll enjoy a sportier and more aggressive sound that adds a dynamic auditory element to your driving experience – striking a perfect balance between performance-oriented sound without being excessively loud. Meticulously designed to integrate with the R53 Cooper S's aesthetics, this Milltek cat-back system will also enhance the visual appeal of your Mini.

This product is a non-resonated system, meaning that it will be louder than a standard exhaust. If you would like a quieter version of this product, take a look at our resonated version of this system today.

Installation of the Milltek cat-back system is designed to be user-friendly, featuring a bolt-on application that minimises the need for extensive modifications. This allows you to enjoy the benefits of an upgraded exhaust system without the complexity of a challenging installation process.
